My teacher asked me to write a total solar eclipse report 10

Partial solar eclipses: Chinese history books say that "solar eclipses are not as good as hooks", and the reason for partial solar eclipses is that the observer falls in the penumbra of the moon, and the observer will see that part of the sun is obscured by the moon's shadow, but the other part continues to glow. The Sun and Moon only partially coincide, and the size of the eclipse is measured by the apparent distance between their centers (the maximum diameter of the Sun covered by the Moon).

Usually partial solar eclipses occur in conjunction with other eclipse phases, such as total solar eclipses. However, some solar eclipses can only be partial solar eclipses (not accompanied by other eclipse phases) because the Moon is so far away from the Earth that only the penumbra touches the Earth's surface.

Annular solar eclipse: When the Moon is at apogee, the Moon's umbral cone cannot reach the Earth; What reaches Earth is a pseudo-umbra cone extended by a umbra cone. The apparent diameter of the Moon is slightly smaller than that of the Sun.

As a result, the ball of light at the edge of the Sun is still visible, forming a bright ring around the Moon's shadow. (Outside the annular eclipse zone, the eclipse seen is a partial eclipse).

Total Annular Eclipse: A total annular eclipse occurs only when the Earth's surface is very close to the tip of the Moon's umbra, or when the Moon's distance from the Earth's surface is very close to the length of the Moon's umbra. Since the earth is a sphere, and the umbra cone touches the earth when it is a total solar eclipse (usually in the middle of the eclipse zone), because the shadow cone fails to touch the earth at both ends of the eclipse zone, only a pseudo-umbra can reach below the earth, and what is seen is an annular solar eclipse.

So, when a total annular eclipse occurs, with the relative motion between the Earth and the Moon, there will be an annular eclipse Annular Eclipse Annular Eclipse Ann The occurrence of a total annular eclipse is rare, the most recent being on April 8, 2005.

This paragraph] summarizes the number of possible solar and lunar eclipses in a year.

There are at least two solar and lunar eclipses in a year, and both of them are solar eclipses;

There may not be a single lunar eclipse in a year (as in 1980);

There can be up to seven solar and lunar eclipses in a year: five solar and two lunar eclipses (e.g., 1935), or four solar eclipses and three lunar eclipses (e.g., 1917 and 1982).

Generally speaking, the most common scenario is that there are four solar and lunar eclipses in a year: two solar and two lunar eclipses.

The above is only for the whole planet. For a certain part of the Earth, there are far fewer chances of seeing a solar or lunar eclipse in a year.

Also, judging from the numbers above, there are more solar eclipses than lunar eclipses in a year, but in reality people tend to see more lunar eclipses than solar eclipses. This is due to the fact that when a lunar eclipse occurs, it can be seen by people on the half of the earth with the sun on their backs; In the event of a solar eclipse, the moon's shadow cone sweeps over only a narrow strip of the earth, and only people in this part of the world can see the eclipse. The lunar eclipse that occurred on the night of March 2, 1961 was visible in China, throughout Asia, and Europe.

The total solar eclipse that occurred on September 22, 1968, only parts of Xinjiang could see the total eclipse in China, only a partial solar eclipse could be seen in Beijing, and nothing could be seen in Shanghai. This solar eclipse in 2009 is once in 500 years, and it can be used in Shanghai, Hangzhou and other places.

A total solar eclipse is a fairy tale written by the sky to the earth!

The sky with a dark curtain quietly came out, the stage was ready, and the moon walked in front of the sun with light steps.

But at this time, we are all looking at the sun, and it is finally changing shape so that everyone can look at it directly.

The shadow of the moon extending from the darkness is just so silently playing its part, assisting in this perfect stage play.

A stage play with the sun as the main character.

It wasn't until the moment when the sun and the moon coincided that we clearly saw the shadow of the full moon, but soon, the sun's rays reappeared in the sky and returned to the earth, a brilliant one, and I still remember that the moon was like a faint volleyball hanging in the night sky during the total eclipse, and I remember staring at the moon for a long time.

When I saw the moon today, I remembered a song. Not "the moon represents my heart", but pink floyd"the dark side of the moon"。Although the moon has been revolving around the earth, there is an area of it that people on the earth will never see, and this is the dark side of moon

I wonder if you knew about this phenomenon before? If you had a chance to see the moon next night, imagine its dark side, wouldn't it feel even more mysterious?

It is the role of the moon that is by our side, running for us every day, silently, just to let us shine brilliantly in our ** period. It's such a character, they are called parents, willing to be a supporting role on our stage, hurriedly walking in front of the dark curtain.

Therefore, as their sun, we should do our best to radiate the light, so that what we most want to see, their smiling faces, will become more and more brilliant in the light.

Today, I was lucky enough to see a total solar eclipse that I had never seen before. Hehe, at that time, the sky was getting darker, it was a spectacle of the moon and the sun coinciding, I went to the 24th floor to look into the distance, the moon gradually swallowed the sun - the end of the world. It's like the one in the movie "Apocalypse", the lucky one, because in ancient times, they didn't understand what it was, and of course, science has explained what it was all about.

Actually, we are all lucky, if we had before, what kind of life would we have? To be sure, it's not as good as it is now. We live in a happy society, at least that's what I think.

When the sky darkened, the light on the street lamp, the light in the car, and the light in the building were intertwined, playing a swan song for the ages.

The total solar eclipse is treasured in my heart like a rainbow, his magnificence, his sacredness, his bravery, his fearlessness, and like a warrior, remain in the hearts of millions of people!

Classmate, you're too lazy, and you don't have a score yet, and no one is estimated to be birding you.

According to astronomical experts, on August 1, 2008, a total solar eclipse will occur on that day. In Jinta County, Jiuquan City, Gansu Province, the Jinding Lake observation site is the best observation point for a total solar eclipse. At **, I worked with many astronomy professors, cave rock experts, and enthusiasts to observe the total solar eclipse.

At about four o'clock in the afternoon, the total solar eclipse was about to begin, and the atmosphere was very solemn, the scientists did the final inspection of the observation instruments, the amateurs were also ready, and we children also prepared the filters. Everyone waited for a long time, I was already impatient, and I began to look around, and just as I was playing, the total solar eclipse began. I saw that the sun was swallowed up little by little by the moon's umbra, and as the minutes and seconds passed, the sun became smaller and smaller, while the moon's umbra became larger and larger.

The sky is getting darker and the air is getting colder, and the observers are hurrying to take pictures and observe the total solar eclipse with a filter. At 7 o'clock in the evening, the sun was almost completely eaten, and a little later, a total solar eclipse occurred, and the moon's umbra completely covered the sun. I don't know how many pieces of the filter were used, I don't know how many times the shutter was pressed, and a few minutes passed, the umbra of the moon slowly left, and the sky slowly returned to light.

At that moment, Bailey's beads appeared, and it was really beautiful! In fact, when the sky is restored to light and the moon's umbra leaves, a piece of light that looks "fat" is revealed, which makes people look very comfortable. The sky slowly re-lit up, and the temperature increased, and now it was time for the "recircle", the moon's umbra slowly left, and the sky returned to light.

At this time, it is more than 8 o'clock in the evening, and the whole process of the total solar eclipse is about 2 hours, and the "total solar eclipse" is only about 4 minutes, which is very rare, this is the first total solar eclipse in the 21st century! I watched this total solar eclipse and wanted to become a doctor of astronomy in the future and explore the mysteries of the universe.
